girl

I thought there was no PIE word for girl because nobody inventen one,
but I see now that someone did invent some tortuous ones. There is now
PIE word for girl and boy. Useless to invent any. But there ARE
cognates if you search hard enough:

boy. No satisfactory explanation has ever been supplied for this word.
Some cognates however are found in Franco-Provençal: Grenoble boya,
Forez boye "young girl", Savoie boya "young cow, girl", Grand-Combe
boyè "young boy", Valais (Switzerland) boyè "young boy, young bull",
Romanian bâiat "boy". These cognates disprove the other etymologies
given for English boy. For the same name being applied to both a young
person and a young animal, cf. English chick "chick and yound girl",
Spanish chica "small and young girl", Greek neossos "chick", neós "boy,
girl", Albanian zogë "chicken, girl", Serbocroatian mladac "fledgling"
mlada "bride", French poule, poulette "chicken, girl".

girl. Cf. German: Switzerland gurrle, gurrli "girl". This name refers
